Public Folder Permissions

Hi people,

I have a Public shared folder, of which I would like to limit users the ability to save or create folder at the root of the P (drive). Windows 2012 Standard 64bit.

E.g.

N:\ (root) - Users permission to view

N:\Folder A\ - Users permission to view, create, modify and delete

N:\Folder B\ - Users permission to view, create, modify and delete

N:\Folder C\ - Users permission to view, create, modify and delete

.

.

.

etc.

Is this possible?

Thank you,

Paul
